Abstract: Curable and/or cross-linkable composition are disclosed and comprise addition-cross-linkable terminal ethylene-group-containing polydialkyl siloxanes and Si—H-group-containing polydialkyl siloxanes having a specific Si—H group content in relation to ethylene groups.

Abstract: Dynamic mixers and methods have a chamber part with a discharge opening, a mixing chamber, a closing part, first and second inlet openings, and a centrical opening. The chamber and closing parts mount against each other in a rotationally symmetric manner and the closing part has substantially parallel planes, wherein a first plane averts a rotor, a second plane faces the rotor, a first inlet opening and a passage opening form a linear duct, and the substantially parallel planes form a feeding duct. Dimensions of the feeding duct are variable depending on a relative rotationally symmetric position of the chamber and closing parts, wherein the dimensions include a length, a width and/or height, and a partial circle is formable by the feeding duct and may enclose an angle of 20-170 degrees depending on the relative rotationally symmetric position of the chamber and closing parts.
